What are the implications of changes in email server policies, such as stricter requirements for sender information in PHP scripts?

Changes in email server policies, such as stricter requirements for sender information in PHP scripts, may result in emails being rejected or marked as spam. To comply with these policies, it is important to ensure that the sender information in PHP scripts is accurate and valid. 

// Set sender information
$from_email = "yourname@example.com";
$from_name = "Your Name";

// Set additional headers
$headers = "From: $from_name <$from_email>" . "\r\n";
$headers .= "Reply-To: $from_email" . "\r\n";

// Send email
$to_email = "recipient@example.com";
$subject = "Subject of the email";
$message = "This is the email message.";
mail($to_email, $subject, $message, $headers);
